Answer:
(-15, 14)
Step-by-step explanation:
Let the coordinates of Z be (x,y).

Answer:
85%
Step-by-step explanation:
To find the percentage we will have to start by dividing the amount he brings home by the gross.
156.4 / 184 = 0.85
By doing this, we get the answer in decimal form, which is not what we want.
Multiply it by 100 to convert it into a percent.
0.85 x 100 = 85.
Now, we know that he brings home 85% of his gross.
15% becomes 0.15
multiply it by 8700
0.15x8700=1305
